We have implemented * in one of our branch offices and recently ran up
against a very strange issue. On random occasions, when we would dial
out using our trunk lines, we would get a message stating “you do not
have to dial a 1 or 0 when calling this number” even if we didn’t dial
a 1 or 0 in the dial sequence at all. After much troubleshooting, we
found users with similar issues that simply put a wait (w$EXTEN) in
the dial sequence and fixed the problems. We did the same and it
automagically fixed itself. This is great, of course, but I was
wondering if someone out there could give me a more detailed
explanation of why this works and why you have to implement this trick
with some telecom providers and not with others. Verison provides our
trunks at our branch office, but this issue has never arisen at our
home office where we have SBC. We are running * v1.0 with a Digium 4
port FXO TDM card.
Thanks,

Simple
Asterisk with either the X100 or the TDM400 doesn't bother to detect
dialtone.
It simply starts dialing, regardless if the CO is ready or not.
It also doesn't bother to detect lack of battery on the line, indicating
a line might be disconnected.
Even very simple telecom devices, such as dial-up modems, for years now
have had that option.
It escapes me why someone felt this wasn't a necessary provision in Asterisk
Too much time on new bells and whistles, and not enough attention to
detail , I suppose.
Can someone smarter than I turn this into a bug report please?
